A compact multiple output power supply which has a circuit architecture with distinct primary and secondary circuit domains. Within the secondary circuit domain, a distribution bus of relatively low constant voltage supplies power inputs to d.c.-to-d.c. converters providing regulated outputs and operating independently of each other. Because of the secondary circuit domain topology, surface mount components are made available in conjunction with relatively simple converter circuitry. Heat management within the compact housing of the power supply is achieved through the utilization of linear driven air flows in combination with employment of heat sinks extending to the heat sink configured cover of the housing. Additionally, the highest heat generation components are positioned rearwardmost within the driven air path.
